The Crosswind is easier to maintain. More rugged, simpler parts...

But hell, the Innova is much more comfortable. I'd only get one after a test-drive, though... make sure that when you go to test-drive it, that the owner hasn't warmed up the engine beforehand... make sure it starts easily (hard-starting is a good sign that the fuel system is on the way out) and that it has no "kalampag".
